“It's a special day for me personally and professionally, but also a day of mixed emotions. I’m excited and humbled to be joining Mercedes next year, which is a huge career step, but it also means I’ll be saying goodbye to my team-mates and friends at Williams. It has been an honour working alongside every member of the team, and an honour to represent the Williams name in F1. Since I joined in 2019, we have worked tirelessly to push each other forward and bring the team back up the grid where it belongs. We’ve battled for every qualifying position, every point, and every tenth of a second. No matter how tough it’s been, nobody has ever given up, and that has inspired me every day. I’ve loved every moment in what I’d describe as a true heart and soul racing team, and I’ll be pushing harder than ever to make sure we end our story in the best possible way.
“Looking ahead to next season, I’d be lying if I said I wasn’t absolutely buzzing. It’s a huge opportunity and one I want to grab with both hands. But I’m under no illusions as to the scale of the challenge; it’s going to be a steep learning curve. Valtteri has set a high bar, consistently delivering week in and week out, scoring wins, pole positions and helping win multiple championship titles."
